DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The method for controlling pests of the present invention comprises the steps of:

(1) treating a seed of soybean, corn or cotton with one or more fungicidal compounds selected from the group consisting of tolclophos-methyl, thiram, captan, carbendazim, thiophanate-methyl, and (RS)-2-methoxy-N-methyl-2-[alpha-(2,5-xylyloxy)-o-tolyl]ace tamide, and

(2) treating a field of soybean, corn or cotton with at least one PPO-inhibiting compound selected from the group consisting of flumioxazin, sulfentrazone, saflufenacil, oxyfluorfen, fomesafen-sodium, and the compound of the formula (I):

before, at or after seeding with the treated seed of soybean, corn or cotton.

In the present invention, the seed of soybean, corn or cotton is not limited as far as it is a variety which is generally cultivated as a crop.

Examples of a plant of such a variety include plants to which resistance to a PPO-inhibiting compound such as flumioxazin; a 4-hydroxyphenylpyruvate dioxygenase-inhibiting compound such as isoxaflutole; an acetolactate synthase (hereinafter abbreviated as ALS)-inhibiting compound such as imazethapyr or thifensulfuron methyl; a 5-enolpyruvylshikimate-3-phosphate synthase inhibiting compound such as glyphosate; a glutamine synthase-inhibiting compound such as glufosinate; an auxin-type herbicide such as 2,4-D or dicamba; or bromoxynil has been imparted by a classical breeding method or a genetic engineering technique.

Examples of a crop to which resistance has been imparted by a classical breeding method include corn resistant to an imidazolinone type ALS-inhibiting herbicide such as imazethapyr, and this has already been commercially available under a trade name of Clearfield (registered trademark). Examples of such a crop also include STS soybean which is resistant to a sulfonylurea-type ALS-inhibiting herbicide such as thifensulfuron methyl. Similarly, examples of a plant to which resistance to an acetyl CoA carboxylase-inhibiting compound such as trione oxime-type or aryloxyphenoxypropionic acid-type herbicide has been imparted by a classical breeding method include SR corn.

Examples of a plant to which resistance has been imparted by a genetic engineering technique include corn, soybean and cotton varieties which are resistant to glyphosate, and they have already been commercially available under trade names of RoundupReady (registered trade mark), Agrisure (registered trademark) GT, Gly-Tol (registered trademark) and the like. Similarly, there are corn, soybean and cotton varieties which are resistant to glufosinate by a genetic engineering technique, and they have already been commercially available under trade names of LibertyLink (registered trademark) and the like. There are corn and soybean varieties under the trade name of Optimum (registered trademark) GAT (registered trade mark), which are resistant to both of glyphosate and an ALS-inhibiting compound. Similarly, there are soybean varieties which are resistant to an imidazolinone-type ALS-inhibiting compound by a genetic engineering technique, and they have been developed under the name of Cultivance. Similarly, there is cotton varieties which are resistant to bromoxynil by a genetic engineering technique, and this has already been commercially available under the trade name of BXN (registered trademark).

A crop such as a soybean which is resistant to dicamba can be produced by introducing a dicamba degrading enzyme such as dicamba monooxygenase isolated from Pseudomonas maltophilia into a plant (Behrens et al. 2007 Science 316: 1185-1188).

By introducing a gene encoding aryloxyalkanoate dioxygenase, a crop which becomes resistant to a phenoxy acid-type herbicide such as 2,4-D, MCPA, dichlorprop or mecoprop, and an aryloxyphenoxypropionic acid-type herbicide such as quizalofop, haloxyfop, fluazifop, diclofop, fenoxaprop, metamifop, cyhalofop and clodinafop can be produced (Wright et al. 2010: Proceedings of National Academy of Science. 107 (47): 20240-20245).

The crop includes, for example, a crop which has become possible to synthesize a selective toxin known in Bacillus genus, using a genetic engineering technique.

Examples of the toxin which is expressed in such a genetically engineered plant include an insecticidal protein derived from Bacillus cereus or Bacillus popilliae; a δ-endotoxin such as Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry2Ab, Cry3A, Cry3Bb1, Cry9C, Cry34ab and Cry35ab, derived from Bacillus thuringiensis; an insecticidal protein such as VIP1, VIP2, VIP3 or VIP3A; an insecticidal protein derived from nematode; a toxin produced by an animal such as a scorpion toxin, a spider toxin, a bee toxin or an insect-specific neurotoxin; a filamentous fungus toxin; plant lectin; agglutinin; a protease inhibitor such as a trypsin inhibitor, a serine protease inhibitor, patatin, cystatin, and a papain inhibitor; a ribosome in activating protein (RIP) such as lysine, corn-RIP, abrin, luffin, saporin or bryodin; a steroid metabolism enzyme such as 3-hydroxysteroid oxidase, ecdysteroid-UDP-glycosyltransferase, and cholesterol oxidase; an ecdysone inhibitor; HMG-CoA reductase; an ion channel inhibitor such as a sodium channel inhibitor or a calcium channel inhibitor; juvenile hormone esterase; a diuretic hormone receptor; stilbene synthase; bibenzyl synthase; chitinase; glucanase; and the like.

A toxin expressed by such a genetically engineered crop includes a hybrid toxin of a δ-endotoxin protein such as Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry2Ab, Cry3A, Cry3Bb1, Cry9C, Cry34Ab or Cry35Ab, and an insecticidal protein such as VIP1, VIP2, VIP3 or VIP3A, and a partially deleted toxin, and a modified toxin. The hybrid toxin can be produced by a new combination of different domains of these proteins using a genetic engineering technique. As the partially deleted toxin, Cry1Ab in which a part of an amino acid sequence has been deleted is known. In the modified toxin, one or a plurality of amino acids of a natural toxin are substituted. Examples of these toxins and recombinant plants which can synthesize these toxins are described in EP-A-0374753, WO 93/07278, WO 95/34656, EP-A-0427529, EP-A-451878, WO 03/052073 and the like. The toxins contained in these recombinant plans impart resistance to Coleoptera vermin, Diptera vermin and Lepidoptera vermin to a plant.

Examples of these genetically engineered plants include YieldGard (registered trademark) (corn variety expressing Cry1Ab toxin), YieldGard Rootworm (registered trademark) (corn variety expressing Cry3Bb1 toxin), YieldGard Plus (registered trademark) (corn variety expressing Cry1Ab and Cry3Bb1 toxins), Herculex I (registered trademark) (corn variety expressing phosphinothricin N-acetyltransferase (PAT) for imparting resistance to a Cry1Fa2 toxin and glufosinate), NatureGard (registered trademark), AGRISURE (registered trademark) CB Advantage (Bt11 cornborer (CB) trait), and Protecta (registered trademark).

In addition, genetically engineered cotton containing one or a plurality of insecticidal vermin-resistant genes and expressing one or a plurality of toxins have already been known, and some of them are commercially available. Examples of these genetically engineered cotton include BollGard (registered trademark) (cotton variety expressing Cry1Ac toxin), BollGard (registered trademark) II (cotton variety expressing Cry1Ac and Cry2Ab toxins), BollGard (registered trademark) III (cotton variety expressing Cry1Ac, Cry2Ab and VIP3A toxins), VipCot (registered trademark) (cotton variety expressing VIP3A and Cry1Ab toxins), WideStrike (registered trademark) (cotton variety expressing Cry1Ac and Cry1F toxins).

Examples of the plant used in the present invention also include plants to which resistance to an aphid has been imparted, such as soybeans into which a Rag1 (Resistance Aphid Gene 1) gene has been introduced.

In addition, the plant used in the present invention also includes those provided with the resistance to nematodes using a classical breeding method or genetic recombination technology. RNAi is exemplified as the genetic recombination technology providing nematode resistance.

The crop also includes a crop to which the ability to produce an anti-pathogenic substance having selective action has been imparted using a genetic engineering technique. As an example of the anti-pathogenic substance, a PR protein and the like are known (PRPs, EP-A-0392225). Such an anti-pathogenic substance and a genetically engineered plant producing the substance are described in EP-A-0392225, WO 95/33818, EP-A-0353191 and the like. Examples of the anti-pathogenic substance expressed in such a genetically engineered plant include an ion channel inhibitor such as a sodium channel inhibitor or a calcium channel inhibitor (KP1, KP4 and KP6 toxins, etc., which are produced by viruses, have been known); stilbene synthase; bibenzyl synthase; chitinase; glucanase; a PR protein; and an anti-pathogenic substance generated by microorganisms, such as a peptide antibiotic, an antibiotic having a hetero ring, or a protein factor associated with resistance to plant diseases (which is called a plant disease-resistant gene and is described in WO 03/000906).

The crop also includes a plant to which a useful character such as oil cake component modification or an amino acid content enhancing character has been imparted using a genetic engineering technique. Examples thereof include VISTIVE (registered trademark) (low linolenic soybean having a reduced linolenic content) and high-lysine (high-oil) corn (corn having an increased lysine or oil content).

Further, stack varieties are also included in which a plurality of the classical herbicide character or herbicide-resistant gene, insecticidal vermin-resistant gene, anti-pathogenic substance production gene, and a useful character such as oil cake component modification or amino acid content enhancing character are combined.

EXAMPLES

Hereinbelow, the present invention will be described by way of Examples, but the present invention is not limited to these Examples.

First, evaluation criteria for an insecticidal effect, a herbicidal effect, and phytotoxicity on crops described in the following examples are shown.

[Plant Pathogen Controlling Effect]

The evaluation of the plant pathogen controlling effect is classified into 0 to 100, in which the numeral “0” indicates no or little disease symptom by plant pathogen as comparison with the untreated crops at the time of the investigation, and the numeral “100” indicates that the disease symptom by plant pathogen is not completely or hardly observed.

[Herbicidal Effect and Phytotoxicity on Crops]

The evaluation of the herbicidal effect is classified into 0 to 100, in which the numeral “0” indicates no or little difference in the state of pre-emergence or growth of test weeds as comparison with the untreated weeds at the time of the investigation, and the numeral “100” indicates the complete death of the test plants or the complete inhibition of their pre-emergence or growth.

The evaluation of phytotoxicity on crops is shown by “no harm” when no or little phytotoxicity is found, “low” when a slight degree of phytotoxicity is found, “moderate” when a medium degree of phytotoxicity is found, or “high” when a severe degree of phytotoxicity is found.
